I have a set on my 04 4.8is and until we got snow here in Chicago they were fine. I put them on in october and driving was a little hard but I chalked it up to stiff suspension. Road noise is also louder than I expected. Well last week we got about 5 inchs of snow and things changed, if you attemp to drive on roads like expressways at higher the 35-40 you are shimying all over. If you try to change lanes while going 35-40 you break free and the rear end wants to do its own thing

. These tires are
NOT All season unless, your fourth season (winter) is in warmer states and you have no snow. They are fine in the winter for driving in town at less the 35, once you get on snow or icy roads all bets are off. For the money, pass on these and get a set of Continental DWS's or Michellan's. These were a waste of money unless you run a summer and winter setup.
I'll be selling these if anyone is interested!!! PM me
